Abstract
A process for purifying batches of liquid hydrocarbons containing antimony hydride comprises passing them over an absorbent material comprising 10-80% by weight of nickel deposited on a carrier, the nickel being present in the form of metallic nickel and in the form of nickel oxide in a ratio of between 2/5 and 2/1 by weight, the amount of metallic nickel being at least 6% by weight of the material. The process is particularly suitable for the purification of streams of propylene destined to be polymerized and for the purification of streams of C4 hydrocarbons.
Description
7 11 PROCESS FOR REMOVING ANTIMONY HYDRIDE FROM LIQUID HYDROCARBON STREAMS
The present invention relates to a process for removing antimony present in the form of a hydride from liquid hydrocarbon streams, In particular batches of hydrocarbons containing substantial amounts of propylene.
In refineries, the treatment of hydrocarbons in liquid form In order to move or to transform impurities requires complex and costly processes. Various antimony compounds, and in particular their hydrides, are uncommon impurities, rarely present at more than one part per million by weight. The antimony may either be present In the starting material used (being present originally in the crude oil feedstock) or may be added in the form of organometallic derivatives before catalytic cracking in order to passivate metallic impurities, In particular vanadium. Nevertheless, even small contents of antimony are generally considered to be unacceptabl e.
Among the liquid hydrocarbon starting materials those containing olefins, and in particular prop lene, are being used more and more..y Present day technology employs highly effective catalysts to convert these starting materials into final products such as polymers.
New processes for polymerizing olefins make use of more and more efficient catalysts. The latter, on the other hand, are extremely sensitive to certain Impurities such as, for example, antimony hydride. In practice this is a powerful catalyst-deactivating agent because of its reducing power. Consequently, when polymerization processes are used it is important to purify the starting material so that the resfdual antimony hydride content is extremely low.
Consequently there is a need for a process which enables antimony hydride to be removed from liquid hydrocarbon starting materials, and more specifically from olefinic hydrocarbons, until the residual content does not exceed 30 ppb (parts per billion by weight, or 1 ng/9) so that the new generation of polymerization catalysts are not poisoned too quickly.
in Belgian Patent No. 902.942 it has been'shown that by passing a stream of liquid hydrocarbon containing COS, in that case a stream of propylene to be polymerized, over an absorbent material consisting of 40 to 70% by weight of nickel deposited on a carrier forming 60 to 30% by weight of the absorbent material, 35 to 70% by weight of the nickel being present in the form of metallic nickel, a COS content not exceeding 30 ppb was obtained.
In published European Patent Application No. 0308569 a process has been disclosed for removing arsine from liquid hydrocarbon streams by passing them over an absorbent material comprising metallic nickel and nickel oxide deposited on a carrier.
The present Invention aims to provide a process for removing antimony hydride from streams of liquid hydrocarbons.
The present invention provides a process for removing antimony present in the form of a hydride from a liquid hydrocarbon stream by passing the stream at a temperature of from -300C to +90C over an absorbent material which comprises nickel deposited on a carrier, the nickel being present in the form of metallic nickel and nickel oxide.
In accordance with a preferred aspect of the present invention it has unexpectedly been found that on passing a liquid hydrocarbon stream, in fact a stream of propylene to be polymerized, over an absorbent material consisting of from 10 to 80% by weight of nickel deposited in the form of metallic nickel and nickel oxide on a carrier forming from 1 j to 20% by weight of the absorbent material, the metallic nIckellnickel oxide ratio being from 2/5 to 211, and the amount of metallic nickel present being at least 6% by weight of the absorbent material, a purified stream was obtained comprising an antimony hydride content not.exceeding 30 ppb by weight. Preferably, a material comprising from 40 to 70% by weight of nickel (total weight of NI + W0) and from 60 to 30% by weight of carrier Is used. If an absorbent material outside these specifications Is used, the antimony hydride may still be absorbed although with less sati sfactory results.
Silica, alumino-silicates, alumina, kieselguhr or other suitable carrier materials may be used as the carrier on which the nickel Is deposited.
The nickel may be deposited on the carrier by any method well known to a person skilled in the art, for example by dissolving nickel nitrate In water, mixing the solution with the carrier and precipitating the nickel, in the form of nickel carbonate for example, and then washing, drying and calcining the precipitate. Then the nickel deposited in this way is partially reduced by means of hydrogen so as to form metallic nickel in an amount of from 34 to 72 molar % of the total quantity of nickel deposited, the remainder being in the form of nickel oxide.
In general, the size of the crystallites of nickel after the reduction is from 1 to 20 nm, and preferably from 1 to 2 mn. The size of the crystallites of nickel depends on, amongst other things, the degree of the reduction performed. In practice If the degree of the reduction is' increased the size of the crystallites Is increased but the absorbent material obtained does not have as good properties. On the other hand, if the degree of the reduction performed Is too low, the size of the crystallItes remains within the limits for good absorption but in this case the quantity of nickel available Is too small to ensure the successful purification of the stream.
The specific surface area of the absorbent material obtained after reduction is generally from 100 to 200 m2/9.
Without wishing to be bound by theory, it is believed that crystallites of too large a size are formed if the NI/M0 ratio is too high, leading to a lower efficiency. Similarly, it is believed that the specific surface area decreases if there is an excess of total nickel, whereas too small a quantity of nickel would lead to an insufficient absorption capacity.
The size of the particles of the absorbent material depends in particular on the extent of removal of material from the stream which is admitted into the reactor. Normally the absorbent material will be used in the form of a powder, pellets, extrudates or balls. Generally the size of the particles of this material will not exceed about 3.5 mm and most often will be from 1 to 3 mm. When extruded particles are used they are preferably multilobed in order to increase the external surface area of the particles and to favour absorption.
Although in accordance with the invention it is possible to treat all kinds of liquid hydrocarbon streams, the process of the invention is particularly adapted to the purification of streams containing light olefins. Usually, liquid hydrocarbon streams containing more than 75% propylene are treated, and more particularly streams containing from 85 to 99% propylene, the antimony hydride content generally being less than 1 ppm.
The process of the invention is also particularly adapted to the purification of streams Of C4 hydrocarbons which have boiling point temperatures close to that of antimony hydride so that easy separation by distillation is impossible.
In one preferred method of performing the process of the present invp-n', ion, the liquid hydrocarbon stream is passed over the absorbent material of the present invention at a temperature generally from -300C to +900C, and preferably from -10C to +400C, and at a pressure sufficient to maintain the medium in a liquid phase.
The hourly spatial velocity by weight, or WHSV, at which the stream is made to pass is usually from 0.1 to 40, and preferably f' c 1 from 1 to 10, depending on the amount of Impurities present In the stream to be purified and the required lifetime for the process.
In one preferred method of performing the process of the invention the previously used absorbent material Is at least partially reactivated by a heat treatment at 150-4500C under a stream of non-oxidizing gas.
The process of the Invention is also applicable to the purification of gaseous ethylene under pressure.
The following Examples are given for the purpose of better Illustrating the process of the present invention but without In any way limiting its scope.
Exampl e 1 A stream of liquid hydrocarbons containing 99% propylene and having an antimony hydride content of 0.85 ppm (parts per million by weight, or 1 mglkg) was passed over an absorbent material consisting of 43.3% by weight of silica as a carrier on which nickel had been deposited and was present In the form of 34% by weight NiO and 22.7% by weight metal 11 c ni ckel.
Before reduction, the absorbent material contained about 49% by weight nickel.
The absorbent material was finely divided so as to consist of particles with a mean size of about 1 mm.
The specific surface area of this material was 145 m%.
The above mentioned stream was passed over this absorbent material at ambient temperature, under a pressure sufficient to maintain the starting material in a liquid phase, and at a WSY (hourly spatial velocity by weight) of 3.6. Less than 30 ppb (the detection limit) of antimony hydride was found in the purified stream.
Example 2
A starting material consisting Of C4 liquid hydrocarbons having the following composition (% by weight) was used 0.02% Cl + C2 0.34% C3 12.77% n-butane 30.22% isobutane 24.04% 1-butene 29.29% 2-butenes 7 -29% isobutylene -50% 1,3-butadiene 0.53% CS and larger hydrocarbons.
The starting material contained 0.75 ppm antimony hydride. This starting material was passed over the same material as that described in Example 1, at a temperature of 250C, under a pressure sufficient to maintain the stream in a liquid phase, and at a WHSV of 3.3.
The purified stream contained less than 30 ppb (the detection limit) of antimony hydride.
The preferred embodiments of the present invention can provide a purification process which enables the removal of antimony hydride from liquid hydrocarbon streams until a residual antimony hydride content less than 30 ppb is obtained.
